feat: add rules argument for getUserInput

[xiaoxustudio]

为getUserInput添加正则验证功能参数

新增参数：

• rule：校验规则，这里的输入将会被视作为一个正则表达式
• ruleFlag：标识，如：g,i等
• ruleText：校验不通过时提示的文本，可用$0获取输入的文本

写法示例：

getUserInput:name -title=如何称呼你 -buttonText=确认 -rule=^.{1,2}$ -ruleText=$0不符合1-2个字符;
WebGAL:很高兴遇见你，{name}！

当正则出现错误时，会跳过验证，并在控制台打印信息

Summary of Changes

Hello @xiaoxustudio, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求旨在通过为 getUserInput 函数引入强大的正则表达式验证功能，显著提升用户输入的质量和可靠性。这一改进使得应用程序能够更灵活地处理用户数据，并在输入不符合预期格式时提供即时反馈，从而优化了用户体验并增强了数据完整性。

Highlights

• getUserInput 功能增强: 为 getUserInput 函数添加了正则表达式验证功能，允许开发者为用户输入设置校验规则。
• 新增参数: 引入了 rule (校验规则), ruleFlag (正则表达式标识，如 g, i), 和 ruleText (校验失败时的提示文本，支持 $0 替换为用户输入) 三个新参数。
• 错误处理: 当提供的正则表达式无效时，系统会跳过验证并打印警告日志，确保程序的健壮性。

Code Review

这个 PR 为 getUserInput 添加了正则表达式验证功能，整体实现得不错。我发现了一个潜在的严重 bug，当 userInput 元素不存在时，代码会尝试访问 null 的属性导致程序崩溃。我已经提供了一个修复建议。另外，我还建议改进验证失败时的错误提示方式，以提升用户体验。请查看具体的评论。

使用 alert() 会阻塞浏览器主线程，并且其样式是浏览器默认的，无法与游戏的 UI 风格统一，可能会给用户带来突兀的体验。建议考虑使用游戏内的 UI 组件来展示错误信息，例如在输入框下方显示一段红色的提示文字。这可能需要将此组件转换为一个有状态的组件来管理错误信息，但能显著提升用户体验。
